Energy Potentials of Agricultural Biomass and the Possibility of Modelling Using RFR and SVM Models

open access: yesEnergies, 2023
Agricultural biomass is one of the most important renewable energy sources. As a byproduct of corn, soybean and sunflower production, large amounts of biomass are produced that can be used as an energy source through conversion.

Cooling panel wall system with difference types of cooling mediums [PDF]

open access: yes, 2020
Global warming has caused worldwide average surface temperature to rise about 0.74oC during the past 100 years, which is partly aggravated by air-conditioning that releases chlorofluorocarbons (CFCs) and forming a vicious cycle.

Radiative heating in the kinetic mode of AGN feedback

open access: yes, 2017
AGN feedback is now widely believed to play a crucial role in the co-evolution between the central black hole and its host galaxy. Two feedback modes have been identified, namely the radiative and kinetic modes, which correspond to the luminous AGNs and ...

Kinetic instability of drift-Alfven waves in solar corona and stochastic heating [PDF]

open access: yes, 2010
The solar atmosphere is structured and inhomogeneous both horizontally and vertically. The omnipresence of coronal magnetic loops implies gradients of the equilibrium plasma quantities like the density, magnetic field and temperature. These gradients are
